70-200 f/2.8L is the best quality lens.

70-200 f/4L has similar quality with 70-200 f/2.8L, but a stop smaller aperature than it. But mobility is the best.

70-200 f/2.8L IS has IS, but the quality is poorest among three.

Does the IS affect the lens quality?

What about Sigma 100-300mm f4? Is it not common?

patwong:

?！70-200 f/2.8L IS 反而係最差呀，乜唔係 IS + f/2.8L 係最 Top 咩，點解 picture quality 會係最差？

Should sell your camera.

[realproa]

If 70-200 F/4 and F/2.8 score mark 95/100 and 70-200 F/2/8 IS score mark 91/100. Could you find the difference in picture quality?

[genewch]

Are there any scientific test reports to compare these 3 lenses? Does IS affect picture quality?

用途都十分需要考慮！
